Call quality issues gone?
I know people's experience will differ based on location, etc.
I live in Beaverton, OR and had a horrible experience tying to use an AT&T iP4 at home. I would drop practically every other call.
My phone arrived at 2:00 p.m. PST yesterday and I have not had a single dropped call at home, work or during my commute home. People mentioned that I sounded like I was calling from a landline. I had crystal clear calls - finally the "almost phone" is a PHONE.
I'm currently using a black NCase from my previous AT&T phone.
I'm loving my new phone!!!
